I don't think mining bitcoina is a waste of energy because the energy you waste, is been paid to you. Yes it depends on the mining hardware you use and also the Electricity bill in your region, but if your are doing a proper Mining then surely you are going to have a good profit. You can cover all the loss of the energy in your mining. If proper hardwares are used then minibg can give us a good profit.

I dont really think that mining is a waste of energy if you earn when doing it. If you are doing it correctly, and you can earn profit less than the expenses you pay for electricity bills, then its never a waste. It can only be a waste if your mining and earn zero.

Then it may be the waste of energy, Remember this is not backed by gold , Bitcoin is backed by Individuals + Scammer + Durg dealers + Politician (black money)

Pepsi is not accepting bitcoin but there vendors are accepting it they are giving backup for this as investment.So you are getting physical Pepsi can by pay bitcoin because a individual is taking bitcoin as investment

If bitcoin is not accepted by Individuals and you cant buy hosting+Pepsi+ physical things then its waste of energy.

With this approach, you can turn everything into a waste of energy. Mining (better to work in warehouse or factory), electric cars (diesel and gasoline can be used), street lights (complete foolishness, candles to everyone), lighting the buildings in the city (again a waste of energy), using a smartphone (some years ago people used to live withput smartphones, I think we dont need it)

Yes, if mining bitcoins is a waste of energy then all the applications you mentioned are also a waste of time. Mining is a business for many. There are also such business which use heavy energy, so are they wasting energy? If we study deeply about a sugar factory then we come to know that huge Electricity ia uaed there to convert sugarcane to sugar. But it is not a waste of energy because we are getting a better output in exchabge with the energy used and so is with mining. We get profit and can cover the Electricity loss.

In each case, income is calculated individually. The same equipment under different conditions can bring different income. Bitcoin evolving transactions go without any problems so it is beneficial. The country in which the miners are is not important.

that's right its calculated accordingly so its not a waste of time even you are not getting the same amount of earnings that someone doesbut for sure if you plan correctly and calculate the outcome then its still useful.

And then there are energy efficient altcoins like the ones that are mined with HDDs or smartphones.

Not the same. Btc mining does not produce anything, gold mining produce, well gold, and banking is a fundamental structure of society. Could we live without banking, sure, but it would be a different world.Btc mining is a wheel thát only supplies it self, and is not linked up to anything else than the trust of users.

It isn’t actually a waste of energy as par say, its just that the energy bills are going to keep piling up and they are going to be eating deep into the mining profit which can make mining unprofitable if the energy cost is high

it sure is.. 1. the only purpose of calculations in mining is making the process of block creation difficult. It is raising the cost of domination to unreasonably high value, higher than potential benefit. Calculations themselves do not add any value to anything. The same could be done by weightlifting if it were automatically verifiable. 2. comparing mining to usage of resources in other activities is bullshit. Using electricity to producing aluminum is different, as without electricity there is no other way to get the metal.3. there are other ways to achieve the same goal, like POS and other proofs that are introduced in other blockchains

Wasted hardly, you buy powerful equipment not just for the sake of interest, and you strive to cover all your expenses, thereby increasing the capacity and costs accordingly. All on increasing. And home mining is definitely a waste of time, energy and energy, the power is not the same and will not cover the costs.

If it that says so, why would all is being intrigue in bitcoin mining if thats a waste of energy. If you're talking about electric energy then I think you should go quit staking or mining as easy as that.
